Neoproterozoic to Cambrian stratigraphy and depositional history of Newfoundland.
Photo: Shoreline outcrop of the Neoproterozoic-Lower Cambrian Chapel Island Formation outside of the town of Grand Bank, Burin Peninsula, Newfoundland. The type section of the Precambrian-Cambrian boundary is placed within these rocks.My PhD dissertation was a study of the Chapel Island Formation, a shallow marine succession of siliciclastic and carbonate strata that straddles the Precambrian–Cambrian boundary. In collaboration with Ed Landing (N.Y. State Museum) and Guy Narbonne (Queen’s University) a main measured section of my thesis (Fortune Head) became the type section of this boundary. I have worked on numerous aspects of these rocks including details of the sedimentary structures and lithofacies, biogenic features, and biostratigraphy. A later study looked at a thin, Neoproterozoic cap carbonate bed at the top the glaciogenic Gaskiers Formation. Finally, in collaboration with Sam Bowring (MIT) and others, we have dated a number of ash beds found stratigraphically below, within, and above the Gaskiers.
